"Has anyone experience with any of these items?"

I have used a Olimex PG2C programmer for some time now. It's a good match for what I do. At $12 to $20 USD it's a good value, but it's got one caveat- no ZIF socket, and you can't add one. the nested design of the socket and the location of the ICSP header prevent that.

But with the ICSP header it'll plug right into the Olimex development board (the first one you posted) and you won't have to remove the chip to reprogram it.

I've bought from Peter Anderson in the past, he's a stand up guy, and I wouldn't hesitate to do bussiness with him again (two of the auctions you linked are his)

Personaly though, I wouldn't buy any of them. You said you have access to a programmer, use it to load a bootloader, then you won't need a programmer.

I use PBP and microCode Studio, I use the bootloader with 16F877A all the time, works like charm. Also- no dev board, I do all my work on a breadboard.

Hope this was helpful enough for my first post.
